In the scorching heat, Felipe Elvira inspects the branches of his olive trees, planted as far as the eye can see on a dusty hillside in southern Spain.

"There are no olives on these. Everything is dry," the 68-year-old said. He and his son own a 100ha (250-acre) olive farm in the southern province of Jaen in sun-drenched Andalusia, a region which produces the bulk of the country's olive oil.
